PCGS Coin Population Scraper — Census / Grade Data

Get PCGS Population Report data — how many coins are graded at each PCGS grade — for any U.S., world, or pattern series. This is the numismatic equivalent of a card population report: for every coin (date, mint mark, variety, designation) it returns the full grade breakdown, from low circulated grades up through MS/PR 70 (including + grades), plus the total graded population and the coin's PCGS number.

Great for coin dealers, collectors, registry-set builders, price-guide makers, and anyone analyzing rarity and grade distribution. (PCGS is the other major coin grader alongside NGC.)

What you get

For each coin in a series:

Input

Navigate the Pop Report the same way the PCGS website does: pick a Region, then optionally filter to a Series by name.

{
"region":"United States",
"series":"Lincoln",
"maxResults":1000
}

Examples

Scrape one specific series directly:

{"seriesSlug":"lincoln-cent-wheat-reverse-1909-1958","seriesId":46}

All Morgan dollars:

{"region":"United States","series":"Morgan"}

China coins, capped:

{"region":"China","maxSeries":5,"maxResults":500}

Notes

• Data comes from the public PCGS Population Report (HTML, server-rendered). Use the residential proxy (default) — PCGS blocks datacenter IPs.
• Grades come from the Comprehensive view, so each coin row includes its full grade spread in one record. Grade labels combine the designation with the numeric grade (e.g. MS65, PR69, MSRD66+).
• populationByGrade only lists grades with a non-zero count, keeping output compact.
• PCGS splits each series into Mint State (MS) and Proof (PR) tables; this scraper merges both into the per-coin output.
